Catalyst is proud to announce the Catalyst Spinathon Challenge, an ambitious, high-energy event taking place across our three sites in the Titanic Quarter, Bedford Street and Derry~Londonderry in support of the Cancer Fund for Children’s 26 Mountains to Mayo campaign.

A team of business leaders is aiming to complete the 26 Mountains 2 Mayo Challenge over 9 days, starting in Donegal on 7th June 2025 and finishing in Mayo on 15th June 2025. During the challenge the team will climb nearly 11,000m, which is 1.25 times the height of MT Everest from sea-level.

Over the course of two action-packed days, Catalyst teams will come together to cycle an incredible 1,185 miles in 10 hours – the equivalent of cycling the distance between the 26 peaks to Mayo, using six high-performance spin bikes.

Cancer Fund for Children is a charity serving families in all 32 counties across the island of Ireland Ireland who are impacted by a childhood cancer diagnosis. Their mission is to support young people and their families emotionally and practically from the point of diagnosis, throughout treatment, and beyond, including times of bereavement.

This isn’t just a fitness challenge. It’s a movement of purpose, community, and compassion.
